But tests are used to see if the implementation corresponds to the
specification.
Since they have no specification, their can't really be any tests.

Or worse, in the absence of a specification, the tests *become* the
specification.

Thus if the first implementation of XXX was stupid all re-implementations
would also have to be stupid (as is the case)
